MP Select Mini 3D Printer V2, Black

The World's #1 Selling 3D Printer*

Too often, getting a low-cost 3D printer means getting a box of ill-fitted parts with poorly written and incomplete documentation. You end up spending hours on the internet, searching forums and asking for help to get the printer assembled and operating properly.

That isn't how Monoprice operates and this 3D printer is a perfect example! This printer not only comes fully assembled, it has already been calibrated at the factory. All you have to do is perform a quick check to verify that the print bed is still leveled, in case it shifted during shipping, then load the included MicroSD™ card, load some filament, and start printing the preloaded model. Nowhere else will you find a 3D printer ready to print out of the box at such a low price!

Why is the V2 only compatible with ABS/PLA when the V1 is compatible with so much more?

BEST ANSWER:Per the product comparison page, this printer supports: ABS, PLA, XT Copolyester, PET, TPU, TPC, FPE, PVA, HIPS, Jelly, Foam, and Felty filaments. Note, however that filament capability is a function of extruder and bed type and temperature range, and this printer should be able to print any material which works within the specified temperature range for this printer.

BEST ANSWER:There a few easy to print and some that dont require printing at all. But essentially you need to prevent the filament from back feeding . I you search MPSM Flex adapter on thingiverse you will find a few options.

BEST ANSWER:There are many advantages and disadvantages to each platform. This is not a simple comparison, The Delta platform we are working on is intended to be easier for a novice to use with Auto Level, Removable build plate.

One thing that I would think about is the difference in a 120mm cube vs a 120mm cylinder. You can print things diagonally and get a little more size for certain prints. That said, I plan on owning both printers.

The heated bed has a nice hard black plastic/rubber liner. Do I need to cover this with tape, or this a new feature to cover the aluminum instead of the tape? Is the black liner replaceable?

A shopper
on Aug 1, 2017

BEST ANSWER:Print directly on the black surface. This is a new design and has worked great for me. No need for tape. I think it is replaceable, I can say mine has seen alot of prints and is still in excellent condition.

What is the largest capacity micro SD card that is compatible with the printer? Mine came with a 1gb card but it doesn't seem to recognize larger cards, such as a 4gb and an 8gb. When I insert a larger card and try to print, it just says that the card is empty even though there are g-code files on it.

BEST ANSWER:If Fusion 360 can output an STL, you can use a slicing program to build the gcode file you will need to print anything on the mini.

You can mod the v2 the same as you can mod the v1 to expand the variety of materials it can print. Out of the box as is, because it uses a bowden extruder instead of a direct drive extruder, there are some limitations to what both versions can handle. The info for the v2 was updated to just reflect the basics to minimize confusion for people new to 3D printing.

The v2 has a bunch of upgrades over the v1, so in theory, it's the better version. It's also the newer version so there may be eccentricities that haven't been sussed out yet, whereas the v1 has been fully community tested.

I make things with Fusion 360 and print them on my Select Mini v1 all the time. V2 is better than v1 because it has a fan to cool the electronics, insulation on the heated bed, and official support for wifi. V1 and V2 both print the same materials, they just didn't list them all for v2.

BEST ANSWER:Yes, it can print metal composites. Although the abrasive nature of these materials will degrade a standard brass nozzle. So, either have replacement nozzles on hand, or switch the nozzle with a hardened or nickel plated brass nozzle.

I am having two issues. 1) When the bed is heading in the farthest position, the pulley is grinding on the power cable zip tie. Is this normal? 2) I am experiencing shifting in both the X and Y Axis. I am printing extremely slow but still does it. Sometimes it is at the beginning layers, while other times it is at the higher levels of a 14 hr print. How do I fix this?

A shopper
on Jun 6, 2017

BEST ANSWER:I dont think there should be any grinding going on.Sounds like something is not right with moving of axis, mine so far seems to be stable and accurate.

BEST ANSWER:In all likeliness the bed wiring is broken and or shorting. Sometime the thermistor detaches from the bed too. There's no fast way to fix it. MP claims to not have parts for it and would prefer to replace it under warranty. To fix it you will have to disassemble the bed and het pad and check every inch of the cable. You'll probably find the wires broken at several points if its like mine was. I cut out the bad spots in the cable and respliced it only to find it was also badly rubbing on everything under the bed. I reran the cable so it goes in and out of the base plate when moving. Some mods involve drilling holes in the back of the base and rerouting the cable outside the base/heat bed. Not a quick fix.

Setup instructions for the mini 3d printer say "standard printer paper". This needs clarified, as printer paper comes in different grades, weights, and thickness. Specifically what kind? Where do we measure, on the metal table or on the pad?

BEST ANSWER:Standard sheet of A4 white paper. You slide the paper between the nozzle and the metal bed. You want to feel slight pressure with the paper, but still able to freely move underneath the nozzle.

Can I put an .STL file on a micro SD card and insert it to print or do I need to attach the printer to a computer?

A shopper
on May 17, 2017

BEST ANSWER:You want to use Gcode with this printer, you can load an STL into your slicer of choice (it comes with Cura) and then put the gcode onto an SD card and print from the card, the best thing to do is to invest in a Raspberry Pi 3 + SD Card and install Octoprint, this will act as a webserver for the printer and will slice STL files for you on the fly.

In order to print an stl file, you'll need to use a slicing program to turn it into g-code that the machine can understand it. Cura and Sli3r are some popular programs.There is a ready to print cat file on the sd that comes with the printer, but otherwise you'll need to use the slicing program to set the "resolution" of the print, the infill, etc. then through WIFI, USB, or Micro-SD you load the file onto the print and print away! Hope this was helpful.

3d printers only print from gcode. You have to open an stl file with a slicer program like Cura and create the .gcode file. Then you can copy the gcode file to an sd card and print it directly from the printer so you do not need to directly connect the printer to a computer.

Reviews

-The print quality is, of course, still excellent. -The hotend seems to be performing much better than the old model. I haven't had any clogs in the weeks that I've owned it. -There is a fan in the back to cool the board. It seems to help, though I think it could do better. I might try a more powerful fan in the future. -The knob, unlike on the V1, is actually usable! Believe me, it's a big deal. -I like the black finish. I also liked the white, but I like the black, too. -The bearings didn't need to be immediately replaced, which is nice.-Leveling was always a struggle for me on the V1. I don't know what's changed (maybe just a non-warped plate), but I haven't had to touch the leveling screws in a month.

Now, there are still a few negatives.

-The spool holder is...not great. You'll need to print a better one at some point, but it'll do for a while. -It's still really noisy. Seriously, you might think something is wrong with it, but that's actually just how it is. I have the Plus as well. I can hardly hear it in the same room. I can hear the Mini down the hall. The V1 was the same.-The hotend, while certainly improved, is a bit confusing if you've followed online discussions. At one point, it was all-metal, then it wasn't, then maybe they were going to send a replacement all-metal one. I don't know what the deal actually is with it, but I'm not worrying too much about it. -My x-axis belt is rubbing...somewhere...and I haven't been able to figure out where. It has become pretty severe, though, so I'm going to have to take it apart eventually to find the cause. It's leaving little black specks on any prints that are too far to the right side of the bed.-That horrible black print surface. Oh my god! My Plus came with it, too, and it's the worst. Just rip it right off as soon as you get it. It's going to come off in pieces on your prints, anyway. Use the bare aluminum with some painters tape until you get something better, if you have to, but do yourself a favor and just don't even start with that black stuff. PEI is good. PrintBite is better and you'll never need to replace it.

Overall, it's a really good printer for the price. I don't think there is another on the market that is a better value. Maybe the upcoming delta, but we'll have to see. If you want to get into 3D Printing, it's probably the best first step into it.

1. Bed heater wires broke after 10 days. A common problem (Google it) that could easily be resolved by short loops of wire that could flex, instead of being restrained by zip-ties.Other than having to fix it myself (knowing that sending it back for a replacement would yield the same result), it's been a great entry-level printer experience.

2. It is only wireless with a phone app... It cannot print from a laptop through your WiFi at home.

3. My experience is the Cura software it ships with, prints fine through the USB cable, but doesn't generate Gcode that can be printed from the SD card. I always need to keep my computer on and hooked-up to print, rather than dropping the SD card into the printer, and printing on-board.

4. I could not get the current Cura software with more parameters to work with this printer.

5. I need to manually "prime" the nozzle just before printing, by forcing a little filament through by hand, or the first edges of my raft do not print, and things go bad from there.

6. The bed is warped. From the factory, mine is high in the center, so leveling the bed at the edges caused nozzle scraping in the center on my first few runs. I now adjust the bed height in the middle of the bed. Not sure how that affects the print quality at the edges.

I just bought one of these at the beginning on May before they went back ordered. I'm completely new to 3D printing but I'm really impressed with the prints this little one is pulling out. I was printing literally 30 mins after opening the box and after leveling the bed as per instructions. PLA results are fantastic but it seems that on large parts a raft is required. Hope it lasts.!

I bought a select mini v2 to compliment my A8, as well as bring 3D printing to my friends. No issues at all- prints well, bed is easy to level. It has been printing almost every day. I would highly recommend to anyone looking to get into 3D printing, on a budget, and without headaches.
